DESCRIPTION

accompanying an application for a Patent for Invention entitled:

"Heating system using a heat pump"

SUMMARY

Heating system comprising a unit? air evaporator, in which the phase of passage from the liquid state to the vapor of the heat exchange fluid is carried out, and a series of radiator elements, arranged in the compartments to be heated, in which the said fluid performs the condensation phase, giving heat to the said environments.

The present invention relates to a heating system using a heating pump. heat and the direct distribution of the primary fluid in the heating bodies.

Purpose of the invention,? that of realizing a plant of the kind mentioned above, in which the use of the intermediate fluid, normally used in known type heat exchange plants, is eliminated, so? to obtain a significant increase in the coefficient of performance, which translates into a corresponding energy saving.

According to the invention, a plant is provided comprising, in combination, a unit? or air evaporating unit, in which the phase of passage of the liquid state to the gaseous state of the heat exchange fluid takes place (for example freon or the like) and a series of radiating elements arranged in the rooms to be heated, connected to said unit , in which. the steam coming from the latter carries out the condensation phase, transferring heat to the surrounding environment.

Said radiators consist of a series of coils connected in parallel, contained in a casing of suitable shape and size, on which many metal wires are welded, thus obtaining in practice a grid of considerable heat exchange.

Will the invention come? now described with reference to the attached drawings, which represent by way of illustration and not already? limiting a preferred embodiment of the invention itself.

In the drawings:

Figure 1 schematically represents the plant according to the invention;

figure 2 shows the detail of a radiator;

figure 3 represents the detail of the evaporator unit, partially sectioned;

figure 4 shows the installation diagram of an autonomous system, in the case of a medium-small apartment, with the evaporator unit placed in a hanging position on a balcony;

figure 5 illustrates the possibility? installation of the evaporator unit on the floor, always on a balcony.

With reference to Figure 1, the number 1 indicates, as a whole, an evaporator unit in which a thermal exchange fluid, for example freon, is evaporated and sent through the delivery pipe 2 to a series of radiating elements. -3-in which the steam, coming from group 1, carries out ... the condensation phase, releasing heat to the rooms. Once condensation has been completed, the resulting liquid is returned to evaporator unit 1. via the return line 4.

From the foregoing, it is evident that the fundamental characteristic of the invention consists in having the operating fluid complete the entire thermal cycle directly, without resorting to an intermediate fluid (water), which entails a significant penalty on the working temperature.

The radiators 3 can be mounted in parallel, as indicated by a continuous line in figure 1, in series-parallel, as indicated by hatching, or simply in series, depending on the location of the various rooms and the volume of the rooms to be heat up

The radiator 3 (figure 2)? consisting of a casing 5, inside which two or more? coils 6 with interposed radiant grids 7, made with metal wire. The coils 6 are connected at the two ends with a pair. of manifolds 8, connected respectively with the delivery duct 2 and with the return duct 4. The radiator 3 can? be both of the static type and of the ventilated type.

The evaporator group 1 can? be placed indifferently in any internal or external room, for example a balcony, both in a hanging position (figure 4) and in a level position (figure 5). Said group 1 (Figures 1 and 3)? contained in a compact casing 9, bearing the base grids 10 for drawing the outside air, by the electric fans 11, and the grilles 12 for exiting the aforementioned air, after which? was forced to go through the evaporation battery, 13.

The fluid in the vapor state, coming from the motor-compressor 14 is sent through the delivery pipe 2 to the radiators 3, where it carries out the. condensation, as already? yes ? said earlier, and returns via tube 4. Before reaching the eva? porator 13, the fluid passes through the filter drier 15, the valve 16 and the capillary 17, which flows into the tube 26. At the outlet from the evaporator 13,? the tube 18 is engaged, which leads the vapor to the liquid separator 19, and from the latter? the tube 20 carries the vapor to the compressor 14, with which the cycle? full?.

The electrical panel 21, which is not described in detail? as known, coordinates and rego? all the automatisms and controls, such as the room thermostat 22, the defrost control 23 of the evaporator, and the cartridge resistance 24, inserted in the liquid separator 19?

The cartridge resistance 24 serves the purpose
